The Greenough 4-C is one of the most classic, fundamental single fin designs for a longboard…ever! 

The man behind this revolutionary fin is George Greenough, whom the surf world is forever indebted to for his wave-riding performance innovations beginning in the 60’s. Greenough paved the way from traditional logging to more progressive surfing in the pocket through the development of his Velo-Spoon kneeboard designs. To complement his kneeboards, Greenough found inspiration from mother nature for his fin templates through studying the tail fins of tuna–one of the fastest and most maneuverable fish in the ocean. The subsequent high-aspect ratio design he created allowed surfers to place themselves in more critical parts of the wave and execute more radical turns; and it ultimately ushered in a new era of high performance capability.

The 4-C is a direct descendant of Greenough’s “Stage 4” tuna fin-inspired designs from the early ‘70s; this iteration was conceived earlier on in the evolution of the Greenough and True Ames collaboration that ultimately led to the 4-A. The 4-C template represents the first step taken in the move away from a traditional pivot fin. Greenough kept the upright nature and minimal rake of a pivot fin, but shaved off a considerable amount of surface area in pursuit of a more high-aspect ratio design. This translates to a higher performance fin that is even more maneuverable, and faster down the line with less drag.

  • Unique design: semi-pivot template but with less area 
  • Works great on all types of longboards 
  • Solid fiberglass construction, flat matte finish

expands work space effectively
Initially it was a bit challenging to set up as I was not fortunate enough to have assistance (the instructions tell you that you need two people for part of the installation process). I also had to play around with placement a bit as my available installation space was extremely limited and neither of the listed/'suggested mounting situations worked for me; however, with some head-scratching and debating with myself, I finally figured how to make it work how and where I needed it it, and all was good!! It functions well, and holds adequate weight, and looks really good with the light lacquer finish...the only thing I will say to a potential buyer is to make sure you have room to walk past it easily when its closed down because it still sticks out a few inches even when closed down...overall, very happy with this item and would purchase again.

Great addition to my sewing table!
I ordered two of these to give me a little more room on my sewing table. One for the backside and one for the left side. Worked out great! Very sturdy and not hard to install (followed directions). I just extended when I need room and fold when not in use. I would recommend these to anyone who just needs a little more table/room.

Not very sturdy
The oak that this is made of is very nice. The little bit of extra counter space is nice. The problem is the bracket to hold it up is kind of small and flimsy, so the shelf won't bear much weight. It will be ok for putting light things on. Also had a problem getting it to hang flat in the down position.
